Specific embodiments

[0023] Now, the utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the utility model in a schematic way, so they only show the components related to the utility model.

[0024] As Figure 1 is the structural schematic diagram of the utility model, an inlaid electric cabinet for an injection molding machine, including an electric cabinet 2 located inside the injection molding machine 1. The electric cabinet 2 and the injection molding machine 1 are connected through a transmission component 3. The transmission component 3 is arranged on the electric cabinet 2. The transmission component 3 is for facilitating the electric cabinet 2 to enter the injection molding machine 1, that is, it can reduce the friction between the electric cabinet 2 and the injection molding machine 1;

[0025] As Figure 5 shown, the transmission component 3 includes a mounting frame 31 and rollers 32. The mounting frame 31 is fixedly connected to the electric cabinet 2, the rollers 32 are rotatably connected to the mounting frame 31, and the rollers 32 are in rolling contact with the injection molding machine 1, facilitating the electric cabinet 2 to enter or move out of the injection molding machine. A positioning groove 53 is opened on the mounting frame 31.

[0026] In this application, the transmission component 3 can also be a slide rail and slider mechanism or other mechanisms. In this regard, this application does not make specific limitations.

[0027] As Figure 2 、 Figure 4 、 Figure 5As shown in the figure, a locking assembly 4 for fixing the transmission assembly 3 is installed in the injection molding machine 1. The locking assembly 4 includes a locking seat 41, a positioning pin 42 and a fixing seat 43. The locking seat 41 is fixedly connected to the transmission assembly 3. A locking groove 411 is formed on the locking seat 41. The axis of the locking groove 411 is parallel to the axis of the positioning pin 42. The positioning pin 42 matches the locking groove 411. The fixing seat 43 is fixedly connected to the injection molding machine 1. The positioning pin 42 is slidably connected to the fixing seat 43, and the positioning pin 42 and the fixing seat 43 are radially fixed, so that the positioning pin 42 can move along its axial direction to enter or disengage from the locking groove 411. A fixing block 431 and a limiting block 432 protrude from the fixing seat 43. A fixing groove 4311 is formed on the fixing block 431. A dial block 421 that matches the fixing groove 4311 and the limiting block 432 protrudes from the positioning pin 42. The dial block 421 is located between the fixing groove 4311 of the fixing block 431 and the limiting block 432. The dial block 421, the fixing block 431 and the limiting block 432 are located on the side of the fixing seat 43 away from the transmission assembly 3. By rotating the dial block 421 forward and backward, it enters the fixing groove 4311 or abuts against the fixing surface 4322 of the limiting block 432;

[0028] In this application, at least one locking assembly 4 is provided for one transmission assembly 3; when one transmission assembly 3 is provided with two locking assemblies 4, the transmission assembly 3 is located between the two locking assemblies 4. When the dial block 421 is located at the fixing surface 4322 of the limiting block 432, a gap for the transmission assembly 3 to pass through is left between the positioning ends of the two positioning pins 42.

[0029] The positioning end of the positioning pin 42 is the end close to the transmission assembly 3.

[0030] When the dial block 421 is located in the fixing groove 4311, the positioning end of the positioning pin 42 is located in the locking groove 411, so as to fix the transmission assembly 3, that is, to fix the electric cabinet 2;

[0031] When the dial block 421 is located at the limiting block 432, the positioning end of the positioning pin 42 is far away from the locking groove 411, so that the electric cabinet 2 can move freely, so that the electric cabinet 2 can enter or exit the injection molding machine 1.

[0032] As Figure 2 、 Figure 5 shown, a limiting ring 422 protrudes from the positioning pin 42. The limiting ring 422 is located between the locking seat 41 and the fixing seat 43. The locking assembly 4 further includes an elastic element 44. The elastic element 44 is sleeved on the positioning pin 42, and one end of the elastic element 44 abuts against the limiting ring 422 and the other end abuts against the fixing seat 43. The elastic element 43 can be a spring. The elastic element 43 can provide an elastic force for the positioning pin 42. After the conversion assembly 5 is positioned and the dial block 421 disengages from the fixing groove 4311, under the action of the elastic force, it automatically enters the locking groove 411 to complete the locking.

[0033] The limiting block 432 has a guiding surface 4321 that expands away from the fixed seat 43 from top to bottom and a vertical fixing surface 4322. The fixing surface 4322 is located below the guiding surface 4321. Through the design of the guiding surface 4321, it can guide the movement of the shifting block 421, making its movement smooth. And under the action of the fixing surface 4322, the detachment of the shifting block 421 is restricted, so that the transmission assembly 3 can move freely and avoid blocking the movement of the rotating assembly 3. When the elastic element 43 is provided, the fixing surface 4322 can provide an abutting effect on the shifting block 421 to restrict its movement.

[0034] As Figure 2 、 Figure 4 、 Figure 5 shown, the injection molding machine 1 is provided with a conversion assembly 5. The conversion assembly 5 is used to control whether the roller 32 contacts the injection molding machine 1, realizing the switching between line contact and surface contact between the electric cabinet 2 and the injection molding machine 1.

[0035] A connecting frame 33 is arranged in the mounting frame 31. The roller 32 is rotatably connected to the connecting frame 33, and there is a gap 34 between the connecting frame 33 and the inner bottom surface of the mounting frame 31;

[0036] The conversion assembly 5 includes a hook 51 and a retaining piece 52. A through hole 311 for the hook 51 to pass through is formed in the mounting frame 31. The through hole 311 communicates with the gap 34. The hook 51 is rotatably connected to the locking seat 41. The height of the gap 34 is less than the thickness of the hook 51. The hook 51 and the retaining piece 52 are fixedly connected. The retaining piece 52 is used to contact the positioning pin 42 to make the hook 51 disengage from the through hole;

[0037] When the electric cabinet 2 and the injection molding machine 1 are in rolling contact, the hook 51 is fitted in the gap 34, so that the roller 32 moves downward to contact the injection molding machine 1, that is, a rigid deformation occurs between the connecting frame 34 and the mounting frame 31, realizing the rolling contact between the electric cabinet 2 and the injection molding machine 1.

[0038] When the electric cabinet 2 moves to the designated position, the retaining piece 52 contacts the positioning pin 42, causing the hook 51 to fall off the gap 34. The connecting frame 34 moves upward a short distance due to the lack of the limit of the hook 51 above, causing the roller 31 to disengage from the injection molding machine 1. At this time, the locking block 41 contacts the injection molding machine 1 to achieve surface contact, increasing the friction between the electric cabinet 1 and the injection molding machine 1, and further avoiding the situation that the electric cabinet 2 moves freely when the locking component 4 is missing.

[0039] After the hook 51 disengages from the gap 34, the locking groove 411 is aligned with the positioning pin 42. Rotate the shifting block 421 to make it disengage from the locking groove 411, and under the elastic force of the elastic element 44, the positioning end of the positioning pin 42 enters the locking groove 411 to complete the locking.

[0040] Based on the above-mentioned ideal embodiments of the present utility model as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
